To me i research Newton theorized and it is now commonly taught that the Earths ocean tides are caused by gravitational lunar attraction. If the Moon is only 2,160 miles in diameter and the Earth 8,000 miles, however, using their own math and law, it follows that the Earth is 87 times more massive and therefore the larger object should attract the smaller to it, and not the other way around. If the Earths greater gravity is what keeps the Moon in orbit, it is impossible for the Moons lesser gravity to supersede the Earths gravity, especially at Earths sea-level, where its gravitational attraction would even further out-trump the Moons.

So you researched "Newton theorized" and now think you know more about something than 300 years of rigorous scientific testing. OK.

You're correct in stating that the Earth is bigger than the Moon, but that doesn't mean that the larger object just attracts the smaller object. Both bodies have influence on each other, and Newtonian physics perfectly predicts how the two objects interact. Although the gravitational pull of the Moon is smaller, it still exists.

The Moon's gravitational pull doesn't need to "supersede" the Earth's to have an effect on it, and therefore that is what we observe - a very slight attraction of the liquid water on Earth, that coincides with the position of the Earth and Moon.

In fact the concept of the Moon being responsible for tidal activity is reinforced when we study spring and neap tides, which change the tidal level depending on the position of the Sun. But I'm sure you already knew that, seeing as you're such an expert on Newtonian physics.

Please explain why spring and neap tides occur, without involving the gravitational pull of the Sun and Moon.
